Summaries for LARS Gene

Entrez Gene Summary for LARS Gene

  • This gene encodes a cytosolic leucine-tRNA synthetase, a member of the class I aminoacyl-tRNA synthetase family. The encoded enzyme catalyzes the ATP-dependent ligation of L-leucine to tRNA(Leu). It is found in the cytoplasm as part of a multisynthetase complex and interacts with the arginine tRNA synthetase through its C-terminal domain. Alternatively spliced transcript variants of this gene have been found; however, their full-length nature is not known. [provided by RefSeq, Jul 2008]

GeneCards Summary for LARS Gene

LARS (Leucyl-TRNA Synthetase) is a Protein Coding gene. Diseases associated with LARS include infantile liver failure syndrome 1 and acute infantile liver failure-multisystemic involvement syndrome. Among its related pathways are Gene Expression and tRNA Aminoacylation. GO annotations related to this gene include aminoacyl-tRNA editing activity and leucine-tRNA ligase activity.

UniProtKB/Swiss-Prot for LARS Gene

  • Catalyzes the specific attachment of an amino acid to its cognate tRNA in a two step reaction: the amino acid (AA) is first activated by ATP to form AA-AMP and then transferred to the acceptor end of the tRNA. Exhibits a post-transfer editing activity to hydrolyze mischarged tRNAs.

Function for LARS Gene

Molecular function for LARS Gene

GENATLAS Biochemistry:
leucyl-tRNA synthetase
UniProtKB/Swiss-Prot CatalyticActivity:
ATP + L-leucine + tRNA(Leu) = AMP + diphosphate + L-leucyl-tRNA(Leu)
UniProtKB/Swiss-Prot EnzymeRegulation:
(5-fluoro-1,3-dihydro-1-hydroxy-1,2-benzoxaborole) inhibits LARS by forming a covalent adduct with the 3 adenosine of tRNA(Leu) at the editing site, thus locking the enzyme in an inactive conformation
UniProtKB/Swiss-Prot Function:
Catalyzes the specific attachment of an amino acid to its cognate tRNA in a two step reaction: the amino acid (AA) is first activated by ATP to form AA-AMP and then transferred to the acceptor end of the tRNA. Exhibits a post-transfer editing activity to hydrolyze mischarged tRNAs.
